Red Bull thinks Mercedes could enjoy a ‘quite powerful’ benefit from its clever rear suspension at some of the remaining Formula 1 races of the season.
Intrigue has surrounded the way that Mercedes has tuned its rear suspension system so that the back end of the car drops down at high speed on the straights.
This behaviour helps reduce drag to boost top speed, and Red Bull believes it played a key part in the advantage that Mercedes had at the recent Turkish Grand Prix.
Red Bull team boss Christian Horner told Sky F1 in the United States last weekend that venues like Istanbul – with a lot of medium speed corners and long straights – was perfect for the Mercedes concept.
"I think that Mercedes are obviously optimising a straightline device that they're able to do at that type of circuit," Horner told Sky in Austin during FP1. "If you look at the rear of their car, how it lowers, I think [Turkey] played to their strengths."
However, tuning the Mercedes system for venues like the Circuit of the Americas, with higher speed turns, is much harder because there is not enough variation between the top corner speeds and the straights.
